SAN JOSE -- A mock gunman training exercise scheduled for Friday at the MLK Library at San Jose State University has been postponed in deference to the shooting rampage in Isla Vista that killed six UC Santa Barbara students, three of whom were from the South Bay.

The training involving the University Police Department, San Jose Police Department, Santa Clara County Sheriff's Office and San Jose Fire Department had been in the works for a year, to fulfill a California State University mandate that it be held once every five years.

But university officials decided that staging a simulated campus takeover by a gunman could be upsetting and disruptive given its proximity to the tragedy in Southern California.

"The events this weekend in Santa Barbara definitely caused us to reconsider," spokeswoman Pat Lopes Harris said. "In many ways, the exercise is more important than ever, but on the other hand, there are three young victims from the South Bay and we want to give their families time and space to deal with the loss of loved ones."
